'The object of my invention is to improve the cfmstruction of my calculating-niachines pending applications, respectively, January 25, 1897, Serial No. 620,630, and September 9, 1897, Serial' No. 651,063.

Said improvements consist in the new construction and arrangements of the several parte, su bstantally as shown in the drawings and hereinafter set forth in regard thereto.

lTo attain said desiredends, I construct and arrange the said several parts of my new ma.- chine substantially as follows, namely:

I make a case a2, in which the bottom, both Y ends, one side, and cover l Wheels all together form one piece. 'l1 he righe hand side a' of said case is removable to in.-

close the con nected interior mechanism, such as is shown inFig. The bottom ofthe 'case' has four rollers a4 parallel to the longitudi- `nal sides of the case, near its corners, to give the machine an easy motion over the pages of ledgers, dec., and to at the saine timelserve as a ruler with which a line ruled on the side-of the machine may be prolonged indefinitely. The case is divided into a series of longitudinal vertical cells by septums l), which rise above the chain mechanism, which they separate, and also pass between and above the notation-wheels, which they also separate, but provide for connecting mechanism between them through openingsb, aXi-.

over the notation- IOC ally coincident with the shaft of said not-.ationwheels. In each of said cells is an endless chain CZ on pentagonal 4rollers or drums c c', the practicable limit of consta-action and use of the chain-lin ks and drums beingsnch as to make the conditions most suitable for a pentagonal drum. Said pentagonal drums tnrn on a rod which passes through the entire series of cells; but the series of drums c' may also be held each on the free end of the platform-lever j by an axis kept within its own cell, constructed as indicated in Fig. 11,

where the long pin s limits the vibration oithe level' and its drnni by a vert-ical slot instead of having the drum fixed, as shown in Figs. l and 2, and where there is a notch s0 ina leg 5 of the lever 7' to limit the amount of vibration ol said lever. 'lhe fnlcrnm of said lever is at l about directly under the drum-shaft h in the arm j of the lever. At the free end of the arm j', forming an 'integral part of the lever .7', there is a rounded and interiorly-notched shoulder-72, which engages with a spur r.2 of a short lever c,.ful crnmed at 2, near the shoulder, and of which the upper edge is in aline with the topline of the leverj. 'lhere is a'n an tit' riction-roller 3 i'n the free end ot' the lever 7c and a like roller 4 in the lower end of the leg at the free end of the leverj, whereof its outer edge has a no'tch s, in whiclrtlle rod s is held and whereby the range of vibration of the levers j 7c is controlled. A long dat spring Z, cen- 'trally held by lugs Z2, presses with one of its' free ends upon the said shoulder of the arm j', and with its end l' it presses against the free end ofthe lever The pin or rod which passes through said lugs and holds all the springs is a'singlepiece which passes through all the cells of the machine.

The chain-links d have verticalspurs d at thcend of each link, which afford agood hold for operating by means of a stylus or pencil, as indicated in Fig. 2, where the end of the stylus at .its starting-point is indicated in broken outlines and in full lines at the end of its stroke, il being arrested by the rod b5 and above the roar drum C, and somewhat farther toward the front are periphcrallytoothed registering wheels or registeringdrums e, one between each t'wo adjacent septnms and for each chain, so placed as to be free ,from said chain-spurs, yet so arranged relatively that the ohain-spnrswill make unfailing contact with the'teeth of the registering-wheels whenever the chains are properly worked with the stylus. The enlarged drawing, Fig. 3l, clearly shows the nature oi the operation of said mechanism. leverj is depressed, the lever 7o rises and contacts -the spurs d' with the spurs of the wheels or drums e, and whenever said lever is released the 'action of the spring l immediatelyT releases said spu rs, and, as shown in the construction in Fig. 3l, stops the action of the chain, because the roller 3 falls into one of the shoulders, or, as here shown, concave the shaft h.

W hen the notches ot the drn n1 c, and -tlins checks fur ther motion. Said action will always Occur becanse of the measured relation of the several parts and is governed by the stylus and its stop b5,.which is arod extending across the entire mechanism at the end of the limit of the travel of the stylus.- Immediately after the stop b5 isa rod with rollers b, lower than the rod bi', under which the spn rs d' pass and strike against said rollers when raised thereto by the lever j, but aiding the action 0f said chain by their rolling motion whenever the chain is again brought into play, and said last action is further facilitated by the roller 4, which depresses the chain under it, and thus drags on the chain part which runs over the roller c' and so brings down the chain at the rollcrb by forcing any kink it of mechanism the cha-in is worked suitably at each of its ends.

The registering-drums are clntmbercd on one. sido only, and from the axial opening outward to near the periphery, while the opposite face is left -a plain surface from the periphery to the ratchet-toothed pinion f, around thcaxialopen ing on vthat side, and in the said drum-chamber is a crescent-shaped lever fr, pivoted at 'r' to the registering-wheel and act-.ed upon by a spring 'r3 at its vouter end, which contacts the side spur r2 with the periphery of a cam g, non-rotatably mounted on lthe' drinn-shaft 7l.. 'lhe said cam has two peripheral faces, one a circular part, to which the wavy surface q' is connected at each end, and at one end oi' said circular face is anotch q2. 'lhe pin r on the inner or camcontact end of the lever r rests and slides on the fac-esci said cam and moves toward and from the axis of the shaft t th rough the action on it ol' the said two faces ot the cam. The pin r2 reaches across said can) and into the notches f2 of the pinion fand is engaged wither released therefrom by the rotation of said cam. The wheels e turn on sleeves f', which are held on the angular edges of the shaft h, or they revolve with said slee-ves on The length of said sleeves is limited by thc cams q, between which they each hold a wheel e, and they pass through the holes b3 of the septums b. Each vwheel e has ten teeth, and radially coincident with said teeth are-teeth f2 on a thereto-fixed pinionf, which are engaged by the pin or spur r2, and said spurs are releasedifroin said teeth by the action ol. the cam q. Said teeth j2 are concaved on their working faces to atford a better holding-surfz-tce against sli ppin". 'lhe motion of said parts q e is in Vthe direction indicated by the arrows, fand when the tenth cog ol. the wheel c is connected with the chain and completes the last part of its revoln tion the face q lets the stud 'r2 into a notch f2 el the notationally next higher wheel and moves it the space of: one tooth, and soon for the entire series of wheelsc. vWhen all the wheels e are to be set to zero, the shaft h is turned IOO IIO

'in the direction indicated by the arrows in Fig. 22,'therchy 4causing the notches q2 to catch the pins r2, respectively, wherever in the circle each may be relatively to the notches q2, which are all in a line parallel with the shaft h and so arranged with the zero-face of the wheel ethat byasingle revolution of said shaft all the wheels e bring their zeromarked faces to the register-opening A.

The shaft h has journal-bearings h' h2 at its ends, and a dat screw-headh4 holds the left-hand end thereof on the outside ot the wall a4, n which the journal-h turns. Beyoud the journal 71,2 is a squared part ha, which enters a square hole in the resetting-wheel o, Figs. 12 and 1'3, and on the inner side of said resetting-wheel are two spurs oi o6, which con tact with a stud 0*, which comesth rough the holo o3 from the free end of a springp, secured to the side plate ci, whereon is a pushpost p', whereby the pin o may be depressed to release the parts '06 o7 of the wheel o from the spur, and by turning said wheel the shaft It and its cams q are turned, effect-ing thereby the resetting of the wheels e, as already set forth. A pawl g, actuated by a spring g2, has' its point thrown against the wheel e to prevent any backward motion of the mechanism. To facilitate the perfect ao tion of said pawl, .its end is beveled at its point g', so as to slip to place and'force the wheel e to recede if it has advanced too far When the chain is raised by the leverj, the spurs will be, approxin'iately, near their place to which they will be corrected, as the np- -7o would actif thechain had notgone farcnough,

the said rollers being so placed as to be between the spurs about as shown.

The hood which covers the notaiion-wl'ieels has at. its top an aluminium plate i lobe used as a tablet for memoranda, held by incnrved So hooks 'z' in transverse chan nels t2, into which the hooks 'i have a .hmctudirnil sliding lit. rlhe intermediate channels #are ol donble. width to receive two adjoining hooks t", and

below the plate 'i-is an adjustable shutter '11",'f`85 held by hooks t'- in said transverse grooves, iff

used for shutting out from View any numbers which it may be necessary to exclude fronrthe register-opening, and still further below is an adjustable decimal point m3 ou'a 9o bodyv m with said hooks '1l' to play in said grooves "i2, and in its body isa screw-stud m2, which plays in a groove with closed ends, whereby it is secured to the machine. There is a like construction for the shutter i" to secure it te its place, as shown. At the front end of the case is a scale, and in the center of each end edge is a hole c, through which pins may pass to lasten the machine to a board or otherwise secure it and by means oi' loo which it maybe hung on a nail. On each '/jj side of the machine, on the walls of the through the momentum imparted to it.

'l'he chain here used has links d, with a cross-head d2 on a neck clsat one end anda ends-d2 fit into thel said correspondinglyrounded cavities d5. Said chain isri gid and f ree from sag against pressure upon the spurface side; buteach link will work with its fellowte about a right-angle position toward the opposite side and is inseparable when in its place. According to the said arrangement all the spurs d' are to be in line across the machine, seen in Figs. 3 and 5, and te form a check for said desired condition. The septuins b are provided with nicks b in line with said spurs. To divide the entire group of chains into sets for various purposes, said septums are made thicker, as shown at b'., Fig. 3, and may be milled or polished or cnt into peaked edges, as shown in Fig. 2S, and the chains themselves may be changed so as to show ditlerent colors or markings, as shown between the septulns b', the arrai'igement, as shown in Fig. 3, being adapted to the computation oE dollars and cents. A set of two rollers n. n' also tends to bring the chain into correct longitudinal position by their action.

are tablets 3', connected to an end tabift s3. On said tablets are doublerows of n'inbers, whereof the outer rows are smaller than the inner rows.

l. The combination with a toothe-d numbering-wheel, of a spurred drun1-snpported iangentially-moving chain to said wheel, a notched platform-lever and stop in said notch and means connect-ed to said lever, provided with antifriction-rollers, to engage and disengage said chain and numbering-wheel, substantially as specified.

2. The combination with a toothed registeringwheel, of a chain-link provided with a spur, vertical to its face, and a slot in the linkhedy with bearings in its sides and a crosshead with neck at the other end of thelink, substantially as specified.
